AGITATOR.

Specification of Letters Patent.

Application filed July 18, 1910.

Patented Sept. 5, 1911.

Serial No. 572,486.

To all whom it may concern:

Be it known that I, JOHN WEMER, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, United States of America, have invented certain new and useful Improvements in Agitators, of which the following is a specification.

My invention relates to agitators for mixing chemicals, and its object is to provide a simple mechanism for holding in a peculiar manner and rotating a receptacle which con tains the matter which is to be acted upon, or different materials or substances which are to be mixed or blended.

To this end I have invented the apparatus which I will describe in the following specification, and the novel features of which I will point out in the appended claims.

Referring to the drawings, Figure l is a side elevation of a simple form of my improved agitator. Fig. 2 is a plan view partly in section of the apparatus shown in Fig. 1 but with the bottle inclined in the opposite direction. Fig. 3 is an end elevation of the same device. Fig. 1 is a sectional end view of the device, the section in this figure being taken on the line 4-4 of Fig. 1. Fig. 5 shows a detail of construction, this figure being a sectional side elevation of the end of one of the clamping members with its adjusting screw. Fig. 6 shows in side elevation, partly in section, a similar part of the other end of the machine.

Like characters of reference designate corresponding parts in all of the figures.

The apparatus comprises a pair of bearing brackets 10 and 11 which are rigidly held together by a cross-brace 12. Near the end of each bracket is a bearing. These bearings are in alinement with each other and one or both of them may be provided with pivoted or removable caps as shown at 13 so that the apparatus may be removed from its bearings. These parts form the stationary portion of the apparatus. i

20 is a rotary member which forms a wheel provided with belt grooves 21 and which has an axially disposed trunnion 22. Across the opposite face of this wheel, at either side of one of its diameters are aflixed ribs 23 which form guides for a pair of sub stantially parallel clamping members 24. These members may be provided with a soft face 25 of some such material as felt. Through their ends run screws 26, 26 each of which is provided with right and lefthand threads, and the ends of which are squared ofi so that they may be readily turned. The ends of the clamp members may be provided with metallic blocks 27 which serve as nuts upon the screws 26.

30 is another rotary member which has a trunnion 31 and guiding ribs 32. The ends of the clamping members are guided between the ribs 23 and the ribs 32 and are held thereby in a plane through the axis of the trunnions 22 and 31.

28, 28 designate longitudinal arms aflixed to the rotary members 20 and 30 at diametrically opposed points between the ribs 23 and 32. The screws 26 pass through these arms and are held in place thereby. Shoulders 29 on the screws abut against the inner surfaces of the arms and prevent longitudinal movement of the screws. The clamping members are so placed on the screws 26 that their corresponding ends will always be equidistant from the axis of the apparatus, although they may be moved toward or away from this axis at will. 33 designates another pair of guiding ribs upon the inner face of the rotary member 20 at right-angles to the ribs 23. 34 is a similar pair of ribs on the inner face of the rotary member 30 at right-angles to the ribs 32. 35, 35 are longitudinal arms aflixed to the two rotary members at points opposite the ends of these ribs. Between ribs 33 and 3 1 and guided by them are two oblique clamping members 36 which may be provided with soft faces 37. 38 designates adjusting screws for these clamping members which screws pass through nuts 39 held against turning by the arms 35 near the ends thereof. There is one such adjusting arrange ment provided for each end of both of the clamps 36.

4.0 is a bottle or other receptacle which is adapted to contain the materials or substances which are to be agitated.

The receptacle may be filled or partly filled with the desired matter and closed by inserting a cork in the mouth of the bottle, and then placed between the clamping members. The arms 28 and 35 are removable so that this may be readily done. Now the clamping members 2 1 are brought toward each other against the sides of the bottle. On account of the construction of their actuating mechanism they will hold the bottle symmetrically in respect of a plane through the axis of the trunnions 22 and 31. I have called these parallel clamping members, to distinguish them'from'the other pair of clamping members, but it is obvious that they are not necessarily parallel in the strict.

sense of the term as thereceptacle need not have parallel sides.

Now, by means of the screws'38 theoblique clamping members 36 are forced down against the sides of the bottle. By them the bottle may be held'at nearly any desired angle and it may be moved backand forth of some kind which are to be dissolved therein the rate of rotationmay be slow enough to simply float the crystals back and forth through the liquidwithout much disturbance of the liquid. i This action may be continued as long as desired which, in some cases, is for several days. Such an action has been found to beef great usefulness; for example, for the purpose of blending liqueurs, and also for dissolving certain crystalline chemicals in certain liquids. In the latter case some substances have been found to be more soluble when subjected to this action than had hitherto been known. Obviously the rate of rotation maybe increased in such cases as require more violent agitation.

What I claim is.-

1. In an agitator, a rotary frame compris ing means for detachably securing a receptacle thereto at different angles oblique to the axis of rotation.

2. In an agitator, a rotary frame comprising means for detachably securing a receptaele thereto at difi'erentangles to the axisof rotation.

3. In an agitator, a rotary frame, clamps combined with said frame adapted to secure a receptacle thereto at different angles to the. axis of rotation.

v 4. In an agitator, a rotary frame compris- Copies of this patent may be obtained for ing clamping members adapted to secure a receptacle thereto symmetrically to a plane through the axis of rotation, and other clamping members adapted to secure the receptacle at diiferent angles oblique to said plane.

5. In an agitator, a rotary frame comprising apair of clamping members adapted to, secure the receptacle thereto symmetrically to the plane through the axis of rotation, screws having right and left-hand threads adapted to move each of said clamping members simultaneously toward or from the axis of rotation, another pair of clamping members adapted to secure the receptacle obliquely to said plane, and adj ustin screws for moving said second pair of clamping members.

6. In an agitator, a rotary frame comprising a pair of clamping members adapted to move radially and to secure a receptacle to said frame symmetrically to a plane throu 'h the axis of rotation, screws having rig it and left-hand threads through opposite ends of said clamping members; a second pair of clamping members adapted to move radially at right-angles to said first clamping members and to secure the receptacle obliquely to said plane, and independent adjusting screws for each end of both of said second clamping members.

7. In anagitator, a rotary frame comprising a pair of clamping members adapted to move radially and to secure a receptacle to the framesymmetrically to a plane through the axis of rotation, guides in the frame for said clamping members; a second pair of clamping members adapted to move radially atright-angles to said first clamping members and to secure the receptacle obliquely to said plane, guides in the frame for said second clamping members, and independent adjusting screws for each end of both of said second clamping members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JOHN WEMER.
